        <div class="class-details">A set that can contain both primitives and objects.  Adding and removing
elements is O(1).  Primitives are treated as identical if they have the same
type and convert to the same string.  Objects are treated as identical only
if they are references to the same object.  WARNING: A goog.structs.Set can
contain both 1 and (new Number(1)), because they are not the same.  WARNING:
Adding (new Number(1)) twice will yield two distinct elements, because they
are two different objects.  WARNING: Any object that is added to a
goog.structs.Set will be modified!  Because goog.getUid() is used to
identify objects, every object in the set will be mutated.
